5 SEED-CUP FOR SEEDlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 241,158, dated May 10,1881.

' Application filed April 5. 1881. (Model) i To all whom it mayconcern.-

' Bcitknown thatI, J oHNR. RUDE, of Liberty, Union county, Indiana, haveinvented a certain new and useful Improvement in Seed-Cups for 5Seeding-llIachines, of which the following is a i specification.

My invention relates to an improvement in the construction of seed-cupsfor seeding-machines of that class which employs a laterally- IO slidingfluted feed-wheel with washers, or rosettes, as they are commonlycalled, recessed in the end wall ofthe cup for the wheel to slidethrough and have its bearing in.

As hitherto constructed, these washers were I 5 simply placed in arecess formed in the inner side of the end wall of the cup, and wereheld in place by overlapping portions of the saddle or of the body ofthe cup when the parts were put together. Such construction isobjection- 2o able on account of the difficulty in making smoothcastings and obtaining a proper fittin g of the parts, which is verynecessary to prevent crushing of the grain and the binding of the wheelor the washer.

2 5 My purpose is to obviate these objections by casting the end wall ofthe cup around the washer in such a manner that the washer is embracedby the cup-wall and becomes practically a part of the same, though freeto revolve.

The novelty consists in the combination, with a feed-cup, of a disk orwasher recessed in the end wall thereof by having the metal of said endwall cast around it in such manner that the periphery of the disk onboth sides is ov'er- 3 5 lapped by the end wall of the cup,whereby,when

said washer is so applied, it becomes practically a part of the cup-walland cannot be removed,

and whereby a smoother and more pefeet hearing is formed, as will beherewith set forth.

In the accompanying drawings, Figure 1 is a central sectional sideelevation of a feed-cup with the wheel and washer in place. Fig. 2 is anenlarged central sectional view through the line 00 00 of Fig. 4. Fig. 3is a corresponding 5 View, representing a modification in theconstruction. Fig.4 is an elevation of the end wall of the cup, with aportion broken away. Fig. 5 is a detail view, showing a secondmodification of the construction.

The same letters refer to like parts in the different figures.

The main portion of the cup A and the feed wheel B maybe of the usual orany suitable construction.

The end wall, 0, containing the washer D, is 55 adapted to fit againstthe main portion of the cup, which it completes, and to which it may beriveted, as at a; and, furthermore, it is provided with lugs I), Fig. 4,by which it may be screwed to the bottom of the hopper E. The washer D,with a central fluted aperture to correspond with the flutes upon thefeed-wheel B, is embraced on both sides of its periphery by the end wallof the cup, as shown in Figs. 1, 2, and 4.

The method of casting the end wall thus around the washer forms thesubject of a separate application which I have made for the process ofcasting a bearing around a circular object, and I will only here brieflyallude to itas follows:

The washer is coated with some adhesive liquid, as asphaltum or shellacvarnish, and then covered with parting-sand to a suflicient depth. Afterbeingdried it is used as acore in the mold 7 5 and the end wall, 0, castaround it. When removed from the mold it only requires a few raps toloosen and break off the sand and varnish, leaving the washer free inits bearing. This process enables me to make a perfectly smooth and truecasting, with the bearing almost as smooth and true as if it had beenturned and polished. By thus inclosing the sides of the periphery of thewasher all danger of cutting or crushing the grain is obviated.

In the above manner of securing the washer in the end wall that shown inFig. 3 may be employed. The only difference in this case is that thewasher, instead of being embraced by the end wall,embraces said endwall, as will be readily understood by reference to the figure.

In using the first form-that shown in Figs. 1, 2,and 4--it is necessaryor advisable to form outlets for the dirt or dust which might accumulatein and finally clog the bearing. This I ob- 5 viate by cutting away orleaving an opening,

0, in the outer lower portion of the bearing, as seen in Fig. 4, or elsebyhavin g a series of those openings, as at d, on the outer side an dextending entirely around the hearing, as in Fig. 5. The only essentialsof these openings are that they should extend as low as the bottom ofthe gutter in which the washer revolves.

Having thus fully described my invention I claim-- 1. In the feedmechanism of a seeding-niaehine of that class which employslaterallysliding and adjustable feed-wheels, the rosette or Washerthrough which the feed-wheel slides, and in which it has its bearing, incombination with and embraced by the end wall of the seedcup, which iseast around it, substantially as described.

2. A feed-cup for seeding-machines, having a rosette or washer for thefeed-wh eel to slide and rotate in cast into the end wall of said cup,substantially as and for the purpose specified.

3. A feed-cup for seeding-machines, having a 20 JOHN R. RUDE.
